Mass Spectrometry

Concept #1: Mass Spectrometry allows you to determine the molecular weight of an unknown compound through its vaporization and ionization. 

A mass spectrometer involves three primary functions: 

1. The vaporization of your unknown compound M into gas M. 

2. The ionization of gas M into the molecular ion or radical cation. 

3. The detection of all gas ion fragments. 

Analysis of all gaseous ions helps to create a mass spectrum.
